Will aftermarket exhaust pass state ref? Visual inspection?
anybody have experience with this?
do they test with db meter to determine whether or not to pass the car?
or they do visual inspection even though it's within 95 db??

If you're in for a noise violation, they will use a dB meter to test your exhaust noise. It doesn't matter what catback u have unless you know for sure it's under 95dB at around 3500-4500 rpms. They will hold the dB meter at a slight angle 18 inches from your exhaust tip and rev and hold your car around the rpms listed above.

Put a stock exhaust on. It's not that hard and will save you a world of headache.
and some refs are a little more mellow on things than others so it's not guaranteed you'll have the same experience as someone else.
I'd hide anything illegal or remove it if you can for the ref then put it back on. Or if its enough stuff just pay the fine and move on.

I agree with OneManArmy...put the stock exhaust back on.
When I was sent to the ref, I put the stock exhaust back on except for an aftermarket axleback (stromung dual tip). I thought it would be quiet enough and I would be able to get it "certified." Well, it didn't pass (I think it was 3 db over) and I had to pay around a 400 dollar fine.

you dont have as much exhaust flow as a WRX/STi would ( because of the displacement/turbo/both ) you may not even have as much exhaust flow as an RS. when i had my Borla header, Apex'i N1 catback, and no cat on my EJ18, an Rs with the same setup would be louder because of the displacement

Unless you have a current decibel test printout that you can show, i wouldn't take the chance.
The law states that the car can not exceed 95dbs (+/-1.5db). So it can be 96.5 dbs and still legal. If you make an appoitment for the db test, make sure your car is at full operating temp, as it makes a difference. They test it a couple times if you don't pass it the first time, due to instrument precision and practice errors

Me too. I passed with the same exhaust. I was cited for emissions on the bov tho. If they actually cite you for noise, then that probably makes things different. But no matter what you get cited for, they're gonna see if your car passes smog. And mine did with my hks exhaust. but they did not do a db test.

Thanks for the inputs!!! appreciated it.
sorry if i didnt make it clear, I don't have any other mods except for Greddy Ti-C catback
i got citation for "Modified Exhaust", i really dont wanna deal with the hassle of swapping the exhaust if i dont have to.
any other advise?
